In PC Advisor (October 2003) XP Workshop has suggested that a EPG (Electronic Program Guide) is not available with Showshifter and that their TV Tuner does not work with one.
Well chaps, I have a Hauppauge WINTV, I have Showshifter and it integrates with Digiguide. Not only that... right-clicking on the Digiguide Page showing "My TV" gives the option of setting a recording time without having to open Showshifter.
It will open, record and close automatically.
I recommend both Showshifter, for its cheapness and Digiguide for its flexibility and cost of £6.99 per year.
I hope PC Advisor will amend its advice because, although it cannot be aware of everything or test every new program, I am sure it would want to keep readers up-to-date with new information relating to its' workshops.
